I love the idea. I assume that it would go on the page listing the different seasons? (
Here). If so, I think its a great idea! The one addition I might recommend is that if the gun is featured as a main characters sidearm, I might add that in the note column. It lets you know the guns that make a random appearance versus the guns that are continually on the show. For example, the SIG-Sauer P228 might have in its note column "sidearm used by most NCIS agents." Just my 2 cents but overall, GREAT idea.
